Rechargeable batteries are beneficial in that you you can reuse them over and over again just by dropping them into a nearby charger for a few minutes or a few hours. But what if you are in a situation where a charger is unavailable or even broken? Now matter how good they are, rechargeable batteries lose their usefulness quickly unless you have a charging unit to power them back up.

That is where the design team of Yeon Kyeong Hwang and Mieong Ho Kang come in. They both have a concept for a new rechargeable battery that not only can get a boost from normal charging stations, but these batteries have the added benefit that you can wind them in order to give them a needed charge.

Not only would these batteries be useful if you didn’t want to carry chargers around with you all the time, these batteries could also be recharged in an emergency where you didn’t have a charger available. Pretty slick stuff. We hope this innovative battery duo finds a backer for their wind-up battery concept very soon.
